The document discusses different ways to represent hierarchical data structures including classical node-link diagrams, nested sets, layered "icicle" diagrams, outlines, tree views, and nested parenthesis notation. Examples of each method are given showing a family tree with Thess-Haydee at the top and relationships between Resty, Allysa, Dharell, Myla and Mikan.
